After you buy the quest, receive a code which grants you access to the quest in the app (the app is free to download). Along the way, find the story of the most prolific executioner in Rome, discover the church of chained spirits, and see the woman who was cursed to lose her hands. Find out many other stories of the people who lived and died in these 10 places that you’ll visit. The quest can be played at any hour, but it is recommended that you try it at night, for the full haunted experience. It will take you from 1 to 2 hours to complete, but there’s no time limit, so you can finish it at your own pace. The total length is about 3.5 km. Each clue will lead you from one place to another, giving you exact directions, so you won’t need a map or GPS. When you solve it and guess the answer, the secret story of that place is unlocked. You won’t need a guide, just download the app, go to the starting point (Piazza del Popolo) and you’re ready to go on a city exploration adventure. For larger groups, one person can purchase access for the entire group by selecting the number of people in the group. All group members will be able to play the city game on their smartphone. Alternatively, each person can purchase their own ticket. You can play as a group and solve the clues together as you walk, or you can split into smaller groups/teams and compete against the others. Each person can also play on their own, separate from the group, and meet the group at the end.
